At the completion of this unit learners will be able
Develop objectives of research
Discuss the research purpose
Explain characteristics of research objectives
Discuss types of research objectives
Describe methods of stating research objectives
Research is an organized investigation of a
problem in which there is an attempt to gain
solution to a problem.
To get right solution of a right problem, clearly
defined objectives are very important.
Clearly defined objectives enlighten the way in
which the researcher has to proceed.
„A research objective is a clear, concise,
declarative statement, which provides direction to
investigate the variables.‟
Generally research objective focus on the ways to
measure the variables , such as to identify or
Sometime objectives are directed towards
identifying the relationship or difference between
Research objective are the results sought by the
researcher at the end of the research process, i.e.
what the researcher will be able to achieve at the
end of the research study.
The objectives of a research project summarize
what is to be achieved by the study.
Objective should be closely related to the
statement of the problem.
6. CHARACTERISTICS OF RESEARCH
Research objectives is a concrete statement
describing what the research is trying to achieve.
A well-worded objective will be SMART, i.e
Specific, Measurable, Attainable, Realistic, &
Research objective should be Relevant, Feasible,
Logical, Observable, Unequivocal & Measurable.
Objective is a purpose that can be reasonably
achieved within the expected timeframe & with
the available resources.
The objective or research project summarizes
what is to be achieved by the study.
The research objectives are the specific
accomplishment the researchers hopes to achieve
by the study.
The objective include obtaining answers to
research questions or testing the research
8. NEED OF RESEARCH OBJECTIVES
The formulation of research objectives will help
Focus: With clearly defined objectives, the
researchers can focus on the study
Avoid : The formulation of research objectives
helps the researcher avoid the collection of data
which are not strictly necessary for understanding
& solving problem that he or she has defined.
Organize :The formulation of objectives organize
the study in clearly defined parts or phases.
Direction: Properly formulated, specific objectives
will facilitate the development of research
methodology & will help to orient the collection,
analysis, interpretation, & utilization of data.
10. TYPES OF RESEARCH OBJECTIVES
1. General objective
General objectives are broad goals to be
The general objectives of the study state what
the researcher expects to achieve by the study in
General objectives are usually less in number.
2. Specific objective
Specific objectives are short term & narrow in focus.
General objectives can broken into small logically
connected parts to form specific objectives.
General objective is met through accomplishing all the
The specific objectives are more in number & they
systematically address various aspects of problem as
defined under „the statement of problem‟ & key factor
that is assumed to influence or causes the problem.
They should specify what the researcher will do in the
study, where, & for what purpose.
12. EXAMPLES OF GENERAL & SPECIFIC
Research statement: “Effectiveness of planned teaching on
the knowledge of staff nurses working in psychiatric unit
regarding Physical Restraints for psychiatric patient in
selected hospital of Lahore”.
General objective: To asses the knowledge of staff nurses
working in psychiatric unit regarding physical restraint.
To assess the knowledge regarding Physical Restraints
among nurses working in psychiatric unit.
To evaluate the effect of planned teaching on Physical
Restraints among nurses.
To associate the knowledge with selected demographic
13. METHODS OF STATING OBJECTIVES
While stating objectives of the study, the following
guidelines must be taken care of:
The objectives should be presented briefly &
They cover the different aspects of the problem & its
contributing factors in a coherent way & in a logical
The objectives are clearly phrased in operational
terms, specifying exactly what researcher is going to
do, where, & for what purpose.
They are realistic considering local conditions.
Use action verbs that are specify enough to be
Examples of action verbs are: to assess, to
identify, to find out, to determine, to compare, to
find, to verify, to calculate, to describe, to
analyse, to establish, etc.
15. STATEMENTS OF PURPOSE
The research goal is often written as a
statement of purpose
It is usually easy to identify because the
word “purpose” is clearly stated- “the purpose
of this study was ….”
gives the general direction of the study
which is stated in 1-2 sentences
16. STATEMENT OF PURPOSE –CONT..
Quantitative studies – it will
identify the key study variables
their possible relations;
17. STATEMENT OF PURPOSE –CONT..
Handwashing helps to prevent the spread of nosocomial
Is the use of soap and water or alcohol-based rubs
more effective in preventing these infections?
Identify the independent, dependent variables and the
State the purpose of the study
18. STATEMENT OF PURPOSE –CONT..
Qualitative studies –
indicates the nature of the inquiry,
the key concept or phenomenon,
the group, community or setting under study
Example: The purpose of this study was to describe
satisfactory and unsatisfactory experiences of
postpartum nursing car from the perspective of
19. STATEMENT OF PURPOSE –CONT..
The use of verbs are important
Can often tell the type of study used to solve
Explore, Describe, Test
Evaluate, Examine relationship
